Stack-based buffer overflow in Python 2.4.2 and earlier, running on Linux 2.6.12.5 under gcc 4.0.3 with libc 2.3.5, allows local users to cause a "stack overflow," and possibly gain privileges, by running a script from a current working directory that has a long name, related to the realpath function. NOTE: this might not be a vulnerability. However, the fact that it appears in a programming language interpreter could mean that some applications are affected, although attack scenarios might be limited because the attacker might already need to cross privilege boundaries to cause an exploitable program to be placed in a directory with a long name; or, depending on the method that Python uses to determine the current working directory, setuid applications might be affected.

Linux kernel before 2.6.13 allows local users to cause a denial of service (crash) via a dio transfer from the sg driver to memory mapped (mmap) IO space.

The SCTP-netfilter code in Linux kernel before 2.6.16.13 allows remote attackers to trigger a denial of service (infinite loop) via unknown vectors that cause an invalid SCTP chunk size to be processed by the for_each_sctp_chunk function.

Buffer overflow in the X render (Xrender) extension in X.org X server 6.8.0 up to allows attackers to cause a denial of service (crash), as demonstrated by the (1) XRenderCompositeTriStrip and (2) XRenderCompositeTriFan requests in the rendertest from XCB xcb/xcb-demo, which leads to an incorrect memory allocation due to a typo in an expression that uses a "&" instead of a "*" operator. NOTE: the subject line of the original announcement used an incorrect CVE number for this issue.

ip_route_input in Linux kernel 2.6 before 2.6.16.8 allows local users to cause a denial of service (panic) via a request for a route for a multicast IP address, which triggers a null dereference.

The sys_add_key function in the keyring code in Linux kernel 2.6.16.1 and 2.6.17-rc1, and possibly earlier versions, allows local users to cause a denial of service (OOPS) via keyctl requests that add a key to a user key instead of a keyring key, which causes an invalid dereference in the __keyring_search_one function.

sql_parse.cc in MySQL 4.0.x up to 4.0.26, 4.1.x up to 4.1.18, and 5.0.x up to 5.0.20 allows remote attackers to obtain sensitive information via a COM_TABLE_DUMP request with an incorrect packet length, which includes portions of memory in an error message.

The check_connection function in sql_parse.cc in MySQL 4.0.x up to 4.0.26, 4.1.x up to 4.1.18, and 5.0.x up to 5.0.20 allows remote attackers to read portions of memory via a username without a trailing null byte, which causes a buffer over-read.

Directory traversal vulnerability in file.c in PHP 4.4.2 and 5.1.2 allows local users to bypass open_basedir restrictions allows remote attackers to create files in arbitrary directories via the tempnam function.

PHP before 5.1.3-RC1 might allow remote attackers to obtain portions of memory via crafted binary data sent to a script that processes user input in the html_entity_decode function and sends the encoded results back to the client, aka a "binary safety" issue. NOTE: this issue has been referred to as a "memory leak," but it is an information leak that discloses memory contents.

Unspecified vulnerability in FreeRADIUS 1.0.0 up to 1.1.0 allows remote attackers to bypass authentication or cause a denial of service (server crash) via "Insufficient input validation" in the EAP-MSCHAPv2 state machine module.

net/ipv4/netfilter/ip_conntrack_core.c in Linux kernel 2.4 and 2.6, and possibly net/ipv4/netfilter/nf_conntrack_l3proto_ipv4.c in 2.6, does not clear sockaddr_in.sin_zero before returning IPv4 socket names from the getsockopt function with SO_ORIGINAL_DST, which allows local users to obtain portions of potentially sensitive memory.

net/ipv4/af_inet.c in Linux kernel 2.4 does not clear sockaddr_in.sin_zero before returning IPv4 socket names from the (1) getsockname, (2) getpeername, and (3) accept functions, which allows local users to obtain portions of potentially sensitive memory.

The SASL negotiation in Jabber Studio jabberd before 2.0s11 allows remote attackers to cause a denial of service ("c2s segfault") by sending a "response stanza before an auth stanza".

The ip_push_pending_frames function in Linux 2.4.x and 2.6.x before 2.6.16 increments the IP ID field when sending a RST after receiving unsolicited TCP SYN-ACK packets, which allows remote attackers to conduct an Idle Scan (nmap -sI) attack, which bypasses intended protections against such attacks.

Buffer overflow in the SetUp function in socket/request.c in CrossFire 1.9.0 allows remote attackers to execute arbitrary code via a long setup sound command, a different vulnerability than CVE-2006-1010.

useradd in shadow-utils before 4.0.3, and possibly other versions before 4.0.8, does not provide a required argument to the open function when creating a new user mailbox, which causes the mailbox to be created with unpredictable permissions and possibly allows attackers to read or modify the mailbox.

Sendmail before 8.13.7 allows remote attackers to cause a denial of service via deeply nested, malformed multipart MIME messages that exhaust the stack during the recursive mime8to7 function for performing 8-bit to 7-bit conversion, which prevents Sendmail from delivering queued messages and might lead to disk consumption by core dump files.

The decompress function in compress42.c in (1) ncompress 4.2.4 and (2) liblzw allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code, via crafted data that leads to a buffer underflow.

BusyBox 1.1.1 does not use a salt when generating passwords, which makes it easier for local users to guess passwords from a stolen password file using techniques such as rainbow tables.
